Functional Magnetic Resonance Imaging

Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.The primary form of fMRI uses the Blood-oxygen-level dependent (BOLD) contrast, discovered by Seiji Ogawa.

… excited or anxious response to stimuli also can be detected by galvanic-skin-response systems that measure bodily secretion of sweat. In addition, researchers can measure the brain’s reaction using functional magnetic resonance imaging.

… stop them from bidding. What do stories actually do to the mind? In a study conducted by the Emory Institute in Atlanta, researchers asked 21 students (12 females) to come for a functional Magnetic Resonance Imaging scan (fMRI’s). The first 5 days were spent taking scans of the initial brain structure and, over the next 9 days, participants were…
